3073 results about "Batch production" patented technology

Batch production is a method of manufacturing where the products are made as specified groups or amounts, within a time frame. A batch can go through a series of steps in a large manufacturing process to make the final desired product. Batch production is used for many types of manufacturing that may need smaller amounts of production at a time to ensure specific quality standards or changes in the process. This is opposed to large mass production or continuous production methods where the product or process does not need to be checked or changed as frequently or periodically.

Thin-film suspended microacoustic resonators for timing applications

A piezoelectric Micro-Electro-Mechanical Systems (MEMS) resonator employs a thin-film piezoelectric layer as an anchor, which eliminates a dominant loss source, anchor loss, which stems from the irreversible mechanical energy radiation through the anchors. By implementing fundamental or higher-order thickness Lame modes (TLMs) in the thickness direction, the piezoelectric resonator exhibits a substantial reduction of thermoelastic damping (TED) and increase of anchor quality factor. The piezoelectric resonator also provides temperature stability by utilizing a substrate with a turnover temperature, minimizing deviation on resonance frequency. This approach enables the use of thin-film piezoelectric materials as anchors, which can be precisely controlled to minimize losses. The piezoelectric resonator's compact design and CMOS-compatibility make it suitable for batch production at a minimal cost per unit. Furthermore, the highly frequency-stable temperature point of the piezoelectric resonator can be used for implementing oven-controlled oscillators for ultra-stable clock generation in various applications.
